Answer 1

Answer:

Answer:

Hence, Relation t is a function. The inverse of relation t is a function.

Step-by-step explanation:

We are given the relation as:

x: 0 , 2 , 4 , 6

y: -10 , -1 , 4 , 8

Clearly from the y-values corresponding to the x-values we could see that each x has a single image (single y-value).

Hence, the corresponding relation is a function.

Now we have to find whether the inverse of this relation is a function or not.

When we take the inverse of this function that is the y-values will behave as a pre-image and x-values as its image.

Hence we will see that corresponding to each y-value there is a unique image hence the inverse relation is also a function.

Hence, Relation t is a function. The inverse of relation t is a function.

Answer 2

Answer: Relation t is a function and the inverse of relation t is a function because each domain element unique and it is paired to an unique range element.

no solutions

Answers

Answer:

D. No solutions.

Step-by-step explanation:

We have been given a system of equations and we are asked to find the solution set for our given system.

$y=x^2-4x-21$

$y=-5x-22$

To find the solution for our given system we will equate our both equations as:

$x^2-4x-21=-5x-22$

$x^2-4x+5x-21=-5x+5x-22$

$x^2+x-21=-22$

$x^2+x-21+22=-22+22$

$x^2+x+1=0$

We will use discriminant formula to check for the solution of our given system.

$√(b^2-4ac) \geq 0$ for real solutions.

Upon substituting our given values in above formula we will get,

$√(1^2-4*1*1) \geq 0$

$√(1-4) \geq 0$

$√(-3) \ngeq 0$

Therefore, our given system has no solutions and option D is the correct choices.

If your annual salary is $68,900, how much would be your salary in 3 years?. Write anEquation and solve the problem

Answers

Answer:

206,700

Step-by-step explanation:

We know that the starting salary is $68,900. And we need to figure out the salary during a 3 years period. so we take the one year salary (68,900) and multiply that by 3, for the 3 years. (3 × 68,900) which equally 206,700 dollars.

Draw a sketch to help you solve this problem. Lucy had 3.2/3 kilograms of apples. She used some of the apples for a dessert. She has 1.1/3 kilogram of apples left.

How much of the apples did Lucy use for her dessert?

Answers

Lucy used 2 1/3 kilograms of apples for her dessert.

Get the whole fraction.

3 2/3 = ((3*3) + 2) / 3 = 11/3
1 1/3 = ((3*1) + 1) / 3 = 4/3

Original weight of apples = 11/3
Remaining weight of apples = 4/3
weight of apples used = ?

Subtracting fractions:
Step 1. Make sure the denominator are the same

11/3 - 4/3

Step 2. Subtract the numerators and put the difference above the denominator

(11 - 4) / 3 = 7/3

Step 3. Simplify the fraction

7/3 = 2 1/3

An employee at plant A receives a salary of $350 per week and a 2.9% bonus on the production sales for the week...If the sales for the week are $5,600, what is her total income?

Answers

If you would like to know what is an employee's total income, you can calculate this using the following steps:

total income = $350 + 2.9% of sales = $350 + 2.9% * $5,600 = 350 + 2.9/100 * 5,600 = 350 + 162.4 = $512.4

The correct result would be $512.4.

The total commission, in dollars, Jessie earned on selling cars at a dealership in two weeks is given by the expression 800+400x. She earns the same amount of commission per car each week. Which situation could be described by this expression?Jessie earned a total commission of $800 in the first week and x dollars in the second week.

Jessie sold 2 cars in the first week and x number of cars in the second week, earning a commission of $400 on each car.

Jessie sold 1 car in the first week, earning $800, and x number of cars in the second week, earning a total commission of $1,200.

Jessie earned a commission of $800 on each car in the first week and $400 on each car in the second week, selling x number of cars each week.

Answers

If Jessie earns the same commission on every car, the 400x part of the equation suggests she earns $400 on each car. If that is the case, in the first week she must have sold 2 cars because 800 / 400 = 2. So Jessie sold 2 cars in the first week and x number of cars in the second week, earning $400 per car.

Answer:

Step-by-step explanation:

Jessie sold 2 cars in the first week and x number of cars in the second week, earning a commission of $400 on each car.
